Abstract

The invention discloses a method for multifunctional sorting of a textile by using a graphene oxide derivative, belonging to the technical field of textile chemistry. The method comprises the following steps: immersing the textile with a graphene oxide derivative water solution; drying the textile and carrying out reduction so that the surface of the textile is covered with one layer of a reduced graphene oxide derivative; and repeating the steps to obtain the multifunctional textile with good conductive, anti-ultraviolet and water-repelling functions. By virtue of the method, the textile can obtain a lot of functions by one type of sorting and the multifunctional sorting of common textiles including cotton, wool, silk, dacron, chinlon and the like, and blended textiles or intertextures thereof can be realized; and the textile can be used for the fields including medical treatment, intelligent sensors, mobile power generation, military affairs and the like.

Description

technical field [0001] The invention belongs to the technical field of textile chemistry, and relates to a method for nitrogen-doping graphene or its derivatives with ultraviolet light to prepare flexible conductive, ultraviolet-resistant and water-repellent fabrics. Background technique [0002] With the improvement of people's consumption level, single finishing products are difficult to meet the needs of the high-end market, composite functional finishing has become a new highlight of product development, and the development of functional textiles is an important way to enhance the competitiveness of my country's textiles. However, at present, the functional finishing methods of fabrics are mostly based on single-functional finishing, because there may be interactions between functional finishing agents, resulting in poor compatibility of finishing agents in the same bath, and the technological conditions of various functional finishing are also different. All the same, s...
